\multicolumn{6}{p{0.93\hsize-10pt}}{\footnotesize \textit{Notes}: $^a$ The average hydrocortisone effect is calculated as in equation~\eqref{eqn: Calculated Hydro Effect}. $^b$ The average coethnicity effect is calculated as in equation~\eqref{eqn: Calculated Coethnity Effect}. $^c$ The interaction effect is given by $\hat{\beta}_3$ in equation~\eqref{eqn: Main Specification}. All terms are described in the text. In this specification, we control for the interaction of a same-gender and same-age group indicator with hydrocortisone as well as gender, age group and ethnicity fixed effects of both players. Standard errors clustered at the participant level. The $ p $-values are column-wise corrected for multiple hypothesis testing following \citet{list2019multiple} using 10 bootstrap draws and are reported in brackets. Significance is denoted by \sym{*} \(p<0.1\), \sym{**} \(p<0.05\), \sym{***} \(p<0.01\).}\\
